As the shepherd leads his sheep,
so did the angel lead the shepherd.
The angel's assignment was to bring wonderful news to the earth. The angel's instructions were to reveal the news to plain humble men sleeping with their animals in the desert. Just imagine how shocked the shepherds were to be the ones worthy of an angel's personal invitation to visit the baby King.
One by one, more angels appeared, and their joyful singing filled the hills around the town of Bethlehem.
Today I add a glorious angel to my Nativity.
